Fucking backwards ass shit. You're damn well on the right track: LLMs tend to avoid swearing (it's kinda funda-fucking-mentally at odds with how most companies want them to be used), so i think we should respond by cursing like sailors, especially creative swears with wordplay and shit.
It doesn't guarantee it's not LLM writing but if nothing else it's more entertaining.

It's not like it's rational, some people's brains are just hard-wired to find them actively pleasurable to look at.
At least that's how it is for me, it's not just a turn-on, it literally just feels good to see a nice pair, to the point that if they perfectly match the variables in my brain it's slightly alarming how close it gets to some sort of eldritch cognitohazard.
But then this applies to almost literally every part of a feminine body, the perfect stomach or neck takes me instantly past the "AWOOOOGA" stage and into drooling vegetable. And all of it on a single person is.. so fundamentally delightful that it actually kinda hurts.
But i'm not sure if this is a universal experience, i get the vibe that i've sorta unlocked this by being sufficiently in-tune with or accepting of my desires. In any case it fucking rocks to the degree that the closest thing i have to religion is "everyone deserves to experience this and be in a relationship with a person who triggers it for them".
